Massachusetts Attorney General Martha Coakley has cited aviation services contractor Flight Services & Systems Inc. for failure to pay workers at Logan International Airport, the second such company at Logan to be fined by the attorney general in the past six months.

Coakley ordered Cleveland-based Flight Services to pay a $1,250 civil penalty and $4,129 to 22 wheelchair assistants and other passenger service agents.

The workers claimed they were paid less than minimum wage and weren’t given meal breaks from November 2009 to November 2012, according to the local chapter of the Service Employees International Union, which has been working with Logan contract employees to improve their working conditions.
